Hi,
It's not clear to me why you would want to do this. As far as I can see,
the purpose of a Tayloe detector is to mix a real-valued RF signal with
a complex-valued local oscillator to arrive at an intermediate frequency
at or near zero frequency that can be sampled using a sound card. If
Sorry for the late reply. I am guessing you are seeing aliases of the
audio signal. Sampling a 1 kHz signal at 32 kHz produces aliases around
multiples of the 32 kHz. In the signal processing chain the sampling
rate will be increased in stages until the DAC sampling rate is reached.

wavelength. Beyond that there's a 4th power law drop off.

I hope this helps.

response said, the centre frequency is zero. If you want
any other frequency, a complex mix is required. To help you understand
this you could try writing some code in Matlab, Octave or Python etc. to
implement a simple signal chain.

Hi,
I am quite new to Gnuradio and Python and have been trying to create my
own functionality using the embedded Python block in GRC. A synchronous
block worked fine but a decim_block complained it was only getting 4
args instead of 5. The doco at
